Due to Apple receiving numerous feedback about loose USB-C connections in earlier 2016/2017 MacBook Pro models, Apple decided to increase the tightness of USB-C ports in 2017 MacBook Pro and even more so in 2018 MacBook Pro models. Users will feel significant resistance in connecting HyperDrive to the 2017/2018 MacBook Pro for the first time, especially for in final 1mm of connection. It is perfectly fine to exert some pressure to make connection for the first time. Subsequent connections will be easier. We have tested ourselves many times and guarantee that your MacBook Pro will not be damaged in any way.
